With Diego Rivera and José Clemente Orozco, David Alfaro Siqueiros was a founder of the renowned school of Mexican mural painting. A Marxist activist since his youth, he fought in the Mexican Revolution and later studied art in Europe. In the early 1930s, he was an influential professor of art in Los Angeles. Later, while in exile from Mexico, he also lived in Chile and Cuba. In this monumental portrait lithograph, he expressed his admiration for Mexican writer, educator, politician, and diplomat Moises Saenz.
